    Pretty sure it's MTP media transfer protocol.

    See, now that's a good question. For wireless music streaming wireless AA, I'm not sure. I would just say via Bluetooth

    The app usually doesn't specify the protocol, it specifies "Bluetooth audio" and lets the system decide. App developers aren't usually system developers. (I've done both over the decades. Let's just say it's like the difference between cleaning up after a mouse and cleaning up after an elephant. But cleaning up after the elephant is so much more fun. [Even if you arrive at work on Friday morning at 8 and don't leave to go home until Saturday morning at 4, as I did one "day". But it felt fantastic when we had solved another "unsolvable" problem.])

    Not sure how technical of an explanation you're looking for, but Android Auto Wireless uses a direct wi-fi connection in order to handle the bandwidth needed, so presumably the music is streaming via direct transfer of data over a direct wi-fi connection (not Bluetooth/A2DP): https://www.cars.com/articles/wirele...ey-now-407297/
